Scrollable GUI's

Vertical and Horizontal scrolling

Haven't tried it with another control that has a scrollbar, but I believe if used with one then will have to use $hwndScrollBar to determine correct scrollbar

Thanks to Holger for pointing me in the right direction and the code to start from

Edit: Removed original script

Test script (include script attached)

Added: Enable/Disable Scrollbars

Added: Hide/Show Scrollbars

Added: Set Scroll Position

Added: Get/Set Scroll Range

Modified: GuiScrollbars.au3 put #include-once in and seperated out the structs

Added: Structs.au3 required for GuiScrollbars.au3

Holy Shiznit! That opens up worlds of opportunities.

Thanks Gary (and Holger) !

This is a really good idea. Lets small gui's hold alot more controls


My Programs:AInstall - Create a standalone installer for your programUnit Converter - Converts Length, Area, Volume, Weight, Temperature and Pressure to different unitsBinary Clock - Hours, minutes and seconds have 10 columns each to display timeAutoIt Editor - Code Editor with Syntax Highlighting.Laserix Editor & Player - Create, Edit and Play Laserix LevelsLyric Syncer - Create and use Synchronised Lyrics.Connect 4 - 2 Player Connect 4 Game (Local or Online!, Formatted Chat!!)MD5, SHA-1, SHA-256, Tiger and Whirlpool Hash Finder - Dictionary and Brute Force FindCool Text Client - Create Rendered ImageMy UDF's:GUI Enhance - Enhance your GUIs visually.IDEA File Encryption - Encrypt and decrypt files easily! File Rename - Rename files easilyRC4 Text Encryption - Encrypt text using the RC4 AlgorithmPrime Number - Check if a number is primeString Remove - remove lots of strings at onceProgress Bar - made easySound UDF - Play, Pause, Resume, Seek and Stop.

@gafrost, I am planning on using this functionality with MDI children, and was wondering if there is a way to create or adjust the scrollbars according to the dimensions of the content?

Here is a (rudimentary) example of what I am doing now:

#include <GUIConstants.au3>
;Opt("MustDeclareVars", 1)
Global Const $WM_CREATE = 0x1
Global Const $WM_HSCROLL = 0x0114
Global Const $WM_VSCROLL = 0x0115
Global $NUMLINES = 50
#cs
    #define SB_CTL              2
    #define SB_BOTH             3
    
    /*
    * Scroll Bar Commands
    */
    #define SB_LEFT             6
    #define SB_RIGHT            7
    #define SB_ENDSCROLL        8
#ce


Global $cyChar, $cxChar, $iMaxWidth, $iVertPos = 0, $iHorzPos = 0

My problem is when a part of regedit is moved outside the boundries of the inner portion of the window. I would like to have a gui that creates scrollbars as needed when the internal window boundries exceed the internal dimensions of the gui window.

EDIT: even this example is unfinished, but it gives you an idea of what I am trying to achieve.

there's probably a good way to calculate the number of lines and columns I just haven't researched it yet

but here's something you could look at

Surprised there doesn't seem to be much interest in this one.

Still if anyone can help make it better I'll gladly accept the help.

After I'm done with my work project Gary, I'll upload the RSS Feed reader I did with it... came in handy since we can't currently use Hyperlinks in the Edit controls themselves.

I'm very interested alright, although I don't feel like posting just to say so ;)

When I saw that you posted this I was thinking of adding it to my current project,

but with the speed I'm currently at it won't be finished before close to Christmas.

I think the basic reason for that is upgraded internet, sickness and pure laziness.

I'll probably post it here some day...if it's ever gets finished that is :whistle:
